Bronze Oak Suspended & Cantilever

Bronze oak suspend & cantilever is a staircase in a private house based on a Sketch Up drawing from the architect. The bronze metalwork of the handrails and bars is actually steel which has had bronze applied. Behind the wood panelling there is a void where we built a timber stud wall to which we screwed a large steel stringer plate. The oak treads have an inner steel frame which we bolted to the stringer and then our wooden cladding slid over hiding the fixings. The suspension bars bolt into the metal frame hidden in each tread and at the top attach to the bottom flange of a very large existing steel beam.

It was this beam's top flange we had to cut a section from to create the riser of the top step. We moved the whole staircase over by a few centimetres and applied a veneer to the web of the beam to create the top riser. Key thing here is that before going to fit on site we could confirm with our SE it would be ok to remove that section from the flange and then explain to the architect there was a problem but that also we had a solution.

The treads are actually 4mm flooring veneer with solid oak for the leading edges but if you zoom in to the ends of the treads you can see the end grain we applied. Those small details are always important to us. (The devil is in the detail)

We later made the two signs shown in the photos.
